Drop the initial reference by fsnotify_init_mark early instead of
audit_tree_freeing_mark() at destroy time.
In the cases we destroy the mark before we drop the initial reference we need to
get rid of the get_mark that balances the put_mark in audit_tree_freeing_mark().

From: Miklos Szeredi
Don't do free_chunk() after fsnotify_add_mark(). That one does a delayed unref
via the destroy list and this results in use-after-free.

Here's the much anticipated re-write of support for level irqfds. As
Michael suggested, I've rolled the eoi/ack notification fd into
KVM_IRQFD as a new mode. For lack of a better name, as there seems to
be objections to associating this specifically with an EOI or an ACK,
I've name this OADN or "

Currently, the sysfs files are updated in a workqueue which is registered in a

I've seen a couple examples recently where we've gotten this wrong.
Maybe something like this would help? Is there some better way?

This fixes a long-standing bug caused by the lack of separate
COMM and EXEC record types, which makes "perf report" lose
track of symbols when a process renames itself.
With this fix (suggested by Stephane Eranian), a COMM (rename)
no longer flushes the maps, which is the correct behavior.

Hi all,
After Dave Airlie blew through a few days to track down a deadlock at boot-up
when handing over from the firmware fb to the kms/drm framebuffer driver (1),
I've
figured that lockdep /should/ have caught this.
And indeed, by adding proper annotations to the console_lock it complains about
Dave Airlie recently discovered a locking bug in the fbcon layer,
where a timer_del_sync (for the blinking cursor) deadlocks with the
timer itself, since both (want to) hold the console_lock:
https://lkml.org/lkml/2012/8/21/36
Unfortunately the console_lock isn't a plain mutex and hence has no

Instead of BUG_ON(in_interrupt()), since that doesn't check for all
the newfangled stuff like preempt.
Note that this is valid since the console_sem is essentially used like
a real mutex with only two twists:
- we allow trylock from hardirq context
- across suspend/resume we lock the logical conso

Arnaldo,
As the libtraceevent library is also used by powertop, and that is
written in *cough* C++ *cough*, we need to make sure that the headers do
not have any C++ reserved words. Please apply this patch. Thanks.

A couple weeks of bug fixing in there. The largest chunk is all the
broken crap Amerigo Wang found in the netpoll layer.
1) netpoll and it's users has several serious bugs:
a) uses GFP_KERNEL with locks held
b) interfaces requiring interrupts disabled are called with them
enabled
